WHAT’S IN THIS BOOK
书中有什么？
As you work through the projects, you’ll increase your knowledge of useful Python libraries and modules; learn more shortcuts, built-in functions, and helpful techniques; and practice designing, testing, and optimizing programs. Additionally, you’ll be able to relate what you’re doing to real-world applications, datasets, and issues.
在完成项目时，您将增加对有用的Python库和模块的知识_学习更多的快捷方式、内置函数和有用的技术_以及实践设计、测试和优化程序。此外，您将能够将您正在做的事情与现实世界的应用程序、数据集和问题相关联。
To quote Ralph Waldo Emerson, “Nothing great was ever achieved without enthusiasm.” This includes the learning experience. The ultimate goal of this book is to spark your imagination and lead you to develop interesting projects of your own. Don’t worry if they seem too ambitious at first; a little diligence and a lot of googling can work miracles—and faster than you think.
引用拉尔夫·沃尔多·爱默生的话，“没有热情就没有伟大的成就。”这包括学习经验。这本书的最终目的是激发你的想象力，并引导你开发你自己的有趣的项目。不要担心，如果他们一开始看起来太雄心勃勃_稍微勤奋一点，大量使用google可以创造奇迹，而且速度比你想象的要快。
The following is an overview of the chapters in this book. You don’t have to work through them sequentially, but the easiest projects are at the beginning, and I explain new concepts, modules, and techniques more thoroughly when they’re first introduced.
下面是本书各章的概述。您不必顺序地处理它们，但是最简单的项目才刚刚开始，并且当新概念、模块和技术首次引入时，我将对其进行更彻底的解释。
